Electrohydraulic Actuator
PVED-CX
The extensive PVG 32 product line now includes a
PVED-CX digital actuator to ensure entrance into the
SIL 2 and CANopen world.
The PVED-CX helps OEM to reach a high performance level while facilitating compliance with the safety demands of Machinery Directive 2006/42/EC.
Target applications are cranes, man lifts, telehandlers and special purpose vehicles.
The CANopen protocol is designed for proportional valve controls and can be used in any application.
Features
•SIL 2 certified according to IEC 61508 by TÜV Süd
•CANopen protocol (CiA 3.01 and CiA 4.08)
•ASSIST (Automatic System Safety Integrity Self Test) feature for Autonomous self-verifying safety system
•High precision valve control
•Low energy consumption

The safety approach of the PVED-CX is based on selfand neighbor-monitoring combined with the ability to shut down all neighbor modules. Spool movement, internal electronics, and software processes are redundantly monitored.
Our complete valve safety concept includes PVG with PVSK.
When using PVED-CX in combination with PVG with PVSK, oil flow is controlled locally by the PVSK. Oil flow to the application can be shut down by both PVSK and valve without influencing other functionality on the vehicle.
PVED-CX – supporting OEMs to meet the required Performance
Level.
